Agave 'Kazo Bana' is one of the best of the gold-edged forms of Agave victoriae-reginae. Kazo Bana, which means "flower of Kazo," was named by Japanese variegated plant guru Yoshimichi Hirose. Our 6-year-old plants are now 6" tall x 10" wide, but we expect them to mature at 10" tall x 18" wide with age...great age. The tight, slowly offsetting clumps of Agave victoriae-reginae 'Kazo Bana' are composed of thick, dark green leaves highlighted by a butterscotch-gold border and topped with attractive white markings. Although most Agave victoriae-reginae are hardy to Zone 7b, I'd recommend growing this to a larger size before trying it outdoors north of warm zone 8. Agave flowers attract hummingbirds.
